2 Claims. (01: 42 65 e 'This invention relates to firearms and, more particularly, to a firearm'in which the receiver and firing mechanism are separable units.

This application is a division" of my pending application, Serial Number 20,740, filed April 18, 1948, entitled Hammer'safety for Firearms, and which matured into Patent Number 2,565,018 on August 21, 1951.

An aim of the invention is to provide a fire arm in which the receiver and the trigger mechanism are separate units and may be simply as- :sembled and disassembled.

A further aim of the invention is to provide an improved arrangement of a simple, economical character for securing the trigger plate to the receiver.

A still further object of the invention is to provide means for securing the trigger plate to the receiver of such character that the securing means is concealed within the receiver so that the securing means does not in any way mar the appearance of the receiver; openings, pins, or the like observable from the sides of the receiver being entirely eliminated.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

The following description will be readily understood by reference to the accompanying drawings in which similar reference numerals refer to similar parts, and in which Figure 1 is a side elevational view of a portion of the receiver and a portion of the stock of the firearm, the receiver being broken away in order to more clearly show the trigger plate, the firing mechanism, and the means for securing the trigger plate'to the receiver;

Fig. 2 is a longitudinal horizontal sectional view taken substantially on line 22 of Fig. 1;

Fig. 3 is a vertical transverse sectional view through the receiver, the same being taken substantially on line 3-3 of Fig. 1;

Fig. 4 is a detail view looking at that portion of the inside face of one of the side walls of the receiver which is provided with the grooves for receiving certain ribs on the trigger plate and the arms of the retaining means; and

Fig. 5 is a perspective view of the retainer for securing the trigger plate in place.

Referring to the drawings, A denotes generally the receiver of the firejarm; only s'ofmnch gi which is shown as is necessary to illustratemy invention, the particular, construction of thereceiver' being immaterial. The receiver is; pro;- vided with sidewalls m and, positioned the're between is a, trigger plate which'carri firing mechanism which is hereishownf prising atrigger l2, asear I3, a hammer I4, and a main spring I5 positioned about a guide rod It. In the present illustrative disclosure. this firing mechanism is substantially the same as that shown in my Patent No. 2,474,180, dated June 21, 1949, and entitled Firing Mechanism.

In accordance with the present invention, the trigger plate has parallel lateral side faces 20 and the width of the trigger plate is such that it closely fits between the side walls I0 of the receiver at the lower rear portion thereof. Projecting laterally from the side faces of the trigger plate are vertical lugs or ribs 2| adapted to fit into vertical grooves 22 in the side walls of the receiver and which grooves are open at their lower ends. The'side faces of the trigger plate are also provided with longitudinally extending grooves 23, and these grooves are complementary to, and are adapt-ed to register with, longitudinally extending grooves I9 in the inner faces of the side walls of the receiver adjacent the lower rear edges thereof. The grooves 19 and 23 may be of any suitable cross section, they here being shown for illustrative purposes as being rectangular.

In order to secure the trigger plate in position within the receiver, retaining means is provided and the same comprises a pair of pins 24 adapted to engage within the registered complementary grooves I9 and 23, as most clearly shown in Fig. 3. If desired, these pins may be separate pieces but, in the present instance, they are shown as being connectedtogether by a cross portion 25 in order to facilitate assembly.

In assembling the trigger plate on the re ceiver, the trigger plate is positioned beneath the receiver so that the vertical ribs 2| register with piece engages the front end of the trigger plate. Accidental withdrawal or displacement of the retaining pins may .be prevented by any suitable means, in the present instance the retainer being shown as held in place by a removable closure plate 26. This plate is adapted to closerthe opening in thefreceiverbetween the trigger plate and the forearm, the latter not being shown.

As many changes couldbe made in the above construction and many apparently widely different embodiments of thisinvention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown' in the accompanying drawings shall be interpreted as illustrative and notinalimitingsense.

It is also to be understoodthat"the'language 'used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scopeof the invention which, asa matter of language, mighii'be said to fall therebetween.

.I Claim as'myinvention: '1. In ,arfirearm, a triggerjplate having sides provided with, longitudinally extending grooves, a receiver having side walls between which said trigger plateis positioned, said side walls having'lo'ngitudinally extending grooves registering with said first-mentioned grooves, and retaining pins located in said grooves for holding the trigger plate in position within the receiver.

2. In a firearm, a receiver having spaced side walls, a trigger plate positioned between said side walls adjacent the bottom, edges. thereof, the opposed faces of said sidewallsfhaving longitudinally extending grooves leading from the ends of the walls and also having vertically extending grooves leading from the bottom edges of said walls, th lateral side faces of said plate having vertically extending ribs engaging in said vertically extending grooves and also having longitudinally. extending grooves complementary to and registering with said first-mentioned longitudinally extending grooves, and retaining pins withinthe registered longitudinally extending grooves;
